Application tiled Ianuar'y 3, 1911. Serial No. 600,513.

Be it known that I, JOHN P. HARaIsoN, Jr., a citizen of the UnitedStates, residing at Ludlow, in the county of Kentonand State ofKentucky, have invented certain new and useful Improvements in AddingMachines, of which the following is a speci- -fication.

. known as ten-key system machines.

"My invention relates to adding machines, particularly to the class ofadding machines My invention'contemplates the provision of an addingmachine employing a series'of keys comprising digits, cipher to nine,and constructed so that the operation of the respective keys will causelateral travel of a carriage having computlng means thereon forarrangingthe computing means in lateral order in columns for formingnumbers.

,My invention further contemplates the provision of recording meansarranged for having operative connection with the addingmechanism of themachine and embracaing laterally movable bars, preferably in the form ofcomputing bars, each of which has the digits arranged insequencethereon, the adding mechanism being arranged to set the bars;and, further, the provisionof totaling means. v

-My invention consists in novel means employed in effecting the results.

It consists further in providmg longitudinally movable computing barsmounted in novel manner; further, inproviding novel means fortransferring the movement of the computing means to the accumulatingmechanism; further in novel mechanism for causing operative engagementand disengagement between the accumulatlng wheels and computingmechanism; further, in novel carry-mechanism; further in novel extended-carry mechanism; further, in novel totaling mechanism; further, innovel total decimaling mechanism; further, in novel mechanism wherebyoperative engagement is main tained during predetermined periods betweenthe accumulating wheels and computing mechanism; further, in providingmeans whereby .when taking a total the means for causing operativeengagement between the accumulating wheels and computing mechain takingtotals.

, be on lateral projections 9 spaced lever mechanism; further in novelactuating means for recording resultants; and the invention willbejfurther readily understood from the following description and claims,nd from the'drawings, in which latter:

Fig.12 is an end view of the therefor and the shaft for the accumulatingwheels and barstops, the supporting shaft therefor and the shaft for theaccumulating wheels being shown in cross-section; and, Fig. 13 is a planview illustrating the carry mechanism between the accumulating wheels,

and showing the equalizing mechanism for the accumulating wheels andbar-stops.

1 represents the main frame of the machine which may be of suitableconstruction.

2 are keys on which the digits from cipher -arranged in a line one infront of the other and acting as stops for bars 8, the fingers being ofa width and arranged in a line so as to affect only one of these bars ata time, and for the purpose some of the fin ers may cm the levers underwhich said projections extend. There is a series of these bars,depending on the number of columns it is desired that the machine shalladd or compute. I have shown the machine of a capacity of six columnsand having six of the bars 8. I shall term these bars computing bars.The machine may also comprise a series of bars 10 which I shall termextended -'carry bars, these latter having the purpose of extending thecarry upon the accumulating-wheels hereinafter mentioned beyond therange of action of said computing bars upon said accumulating wheels.The bars are mounted on a carriage 11 which is movable laterally onsuitable guideways on the main frame, shown in the present instance as arod 12, at the rear of the carriage slldable longitudinally in bearings13 of the main frame and a track 14 which rides upon a roller 15suitably journaled in the main frame. The bars are shown spaced apart.The spacing of the bars is preferably accomplished by being received inslots 16 of a transverse plate 17 and by having the earriage-rod 12provided with grooves 18 in which the bars are received.

The bars 8 are provided with shoulders 20, (see Figs, 4 and 6), arrangedto respectively engage the finger on the key-lever 3 which may bedepressed, for determining the longitudinal position of the .bar uponthe depressing of the key.

The bars 8 are normally locked in retracted positions by pawls 21, oneof whiclris provided for each bar, the pawls being pivoted on thecarriage on the pawl-rod 19, and normally held into engagement with theteeth of ratchet-racks 23, respectively on the respective bars 8, bymeans of springs 24. (See'Figs. 4 and 8.) Each of the pawls is providedwith a tail 25.; These tails are successively acted upon, when broughtby the lateral movement of the carriage under a trip 26, which is shownon a trip-bar 27 having clearance-spaces 28 29 at either side of thetrip so as to avoid contact by the trip-bar with any of the pawls exceptthe one which is momentarily located under the trip 26. (See Figs. 2, 4and 5.) The trip-bar has forwardly extending arms 30, the forward endsof which are pivoted at 31 to the main frame.

is a universal barreceived under the key-levers 3 and arranged to bemoved by any of the latter. It has side-arms 36 which are pivoted to themain frame about the rod 4 upon which the key-levers are pivoted.

. The arms 36 and 30 are connected by links 37 for transferring themovement of each of the key-levers 3 through the medium of theequalizing bar to the trip-bar, irrespcctive of which key-lever 3 may beoperated.

Upon operation of' a key-lever 3, the equal izing bar is depressed,which, through the .rack on the computing bar which is in S'ItlOIl forengagement, dependent on the lomedium of the links 37, depresses thetripbar, the trip whereon depresses the tail of the pawl which may bethereunder, thereby raising the pawl .and permitting the computing barthe-:eunder to be moved b means of a spring 38 until the shoulder 20 onthe computing bar strikes the finger 7 of the key-lever 3 which has beendepressed, thereby stopping the advance movement of the computing-bar,and locating the said bar in the proper position for computation inmanner to be hereinafter described, Each of the.bars 8 and 10 has aspring 38 applied thereto, one end of the springs being secured to-a rod39 in the frame 11. When the key-lever 3 is released, the pawl willfirst engage the tooth of the ratchetcation of the finger of thekey-lever 3 which hasbeen depressed, for longitudinally locating thecomputing bar for subsequent operation in a manner to be presentlydescribed. A spring 40 between the trip-bar and rod 4 normally retractsthe trip-bar and universal bar. Springs 41 between the keylevers andframe normally retract the key levers, the latter being operative inslots 42 of a plate 43 on the frame. Upon retraction of the key-lever,the carriage 11 is advanced laterally one space, under the influence ofa spring barrel 44 which has afiexible connection 45 with the carriage 3whereby the computing bar first acted on will be advanced to the columnof next higher order. Upon each depression of any of the keylevers, thecomputing bar in the location of the last column reached in the numberbe: ing formed on the machine will be acted on. This advance of thecarriage is controlled by the escapement 51, (see Figs. 1, 2, 5 and 7,)shown consisting of a ratchet-rack 52 011 the carriage and escapementpawls 53 54, of which 53 is a laterally rigidpawl and 54 is a laterallyslidable pawl, retracted by the spring 55. The pawls are mounted on onearm 56 of a bell-crank rocker 57, the other arm 58 of which is operatedby a link 59 articulated to the trip-bar, and having an end-slot 60received over a pin 61 on the arm 58, the end-slot 60 being provided forpermitting the escapement to be operated by the cipher key withoutoperation of the trip-bar. The escapement is retracted to normalposition by a spring 63. The normal longitudinal position of each of theoperating the same when the cipher-kc is depressed.

Assuming that it is desire to preduce the number 501, the 5 key isfirstdepressed, which releases the first of the computing bars, and onretraction of ,the 5, key, the carriage will move one space to theleft,bringing the next bar into range of the fingers 7 The cipher keybeing operated, leaves the coin uting bars longitudinally inactive, buts ifts the carriage one more space. Operating the 1 key, acts "on thethird computing bar and the carriage is again shifted one space to theeft. This places the computing bars and carriage in proper operativerelation to the accumulating wheels and recording mechanism. 7

There is. a series of accumulating wheels 65, shown as spurwwhe els.(See Figs. at, 5, 6, 8 and 13.) The bofnputing bars are provided with.toothed racks 66, which I shall term accumulatin -racks, with which theaccumulating whee s are arranged to mesh.

Each of the accumulating wheels is shown as comprising a double seriesof ten teeth each, namely twenty teeth, there being a super-depression67 in the respective wheels .at the ends of the respective series of tenteeth. These accumulating wheels are ar-. ranged to. rotateindependently of each other, but are under the influence of theaccumulating racks and of novel carrying mechanism to be presentlydescribed. The accumulating wheels are normally out of engagement withthe accumulating racks of the computing bars and are normally locked inposition by having a locking-bar 68 re ceived in the depressions betweentheteeth of the accumulating wheels.

The carry mechanism comprises stops 71 in connection with which latches.72 are adapted to operate. There is preferably a stop in line with eachaccumulating wheel for acting on the bar in mesh -with said wheel. Thestops are pivoted about a rod 73 and the latches about a rod 74. The

latches are normally held in engagement with the stops by springs 75connected to said respective stops and latches, retracting movement ofthe stops being limited by the stoprod 76. The stops limit theretraction of the computing bars and extended-carry bars. Each bar isprovided with a contactpart 78 arranged to engage the stop. The stopsarrest the bars at two predetermined points, one when the latch isinengagement with'the stop, and an accumulation is taking place within therange of the accumulating' wheel acted on, and the other when the latchis disengaged and there is a carry from an accumulatingwheel of lower toone of higher order, resulting in a movement of one tooth in the wheelof higher order. The extended-carry bars are located above theaccumulating wheels and Step an-d the he ment required in said bars.latches are arranged to act in conjunction gers 7 are located above thecomputing bar of ultimate highest order, during'normal position ofthecarriage. When the carriage is moved one space to the left, all thebars 8 and 10 will be moved. therewith, and the first or left-handcomputing bar will be located above the last or right-hand accumulatingwheel.- The extended-carry bars serve the purpose of accumulating thecarries into the accumulating wheels which are latorally to the leftbeyond the range of the computing bars. Thus assuming that only thefirst computing bar is in engagement with the last accumulating wheel,and the total added into the last five accumulatin wheels is 99,999, andthe amount to be added by the engagement just stated is 5, the operationof the operating lever will cause all of said extended-carry bars to actfor accumulating the sum of 100,001 into said wheels. The extendedcarry-bars have but a limited movement, suflicient ,to effect theturning of an accumulating wheel one tooth. For this purpose theextended-carry bars are provided with short slots 79, through which therod 12 extends, the end-walls of the slots limiting the longitudinalmovements of the extended-carry bars. (See Fig.

11.) These bars also have short racks 80 with which the accumulatingwheels are adapted to mesh. The computing bars have longer slots 81 inwhich the rod 12 is received to permit the greater rangeof move- Thesteps and with the accumulating wheels for carrying from a wheel oflower order to a wheel of higher order.

The latch for the stop of the first or column of lowest order is notihowever provided with releasing means, as :m operation no carry istransferred to this wheel.

The latches 72 have tails 82 adapted to be engaged by pins 83 on theaccumulating wheels respectively of next lower order.

The tails 82, in the form shown, serve twopurposes, one of which is torelease the latch from the stop 71 when there is a carry, at which timethe accumulating wheel r0.- tates in the direction of the arrow a, (seeFigs. 6, 8 and 11,) and the other of which is to act as a stop for theaccmnulating wheel when taking a total, in manner to be hereinafterdescribed, at which time the accumulating wheels rotate opposite to thedirection of the arrow a, for arresting the rotation of the accumulatingwheels at a point corresponding to zero, and thus clearing the machine.It will be noted, (see Fig. 13), that these. tails project laterallyfrom a latch in line with an accumulating wheel of higher order to anaccumulating wheel of lower order, the accumulating wheel of .lowerorder thereby efiecting a carry into .an accumulating wheel of higherorder.

The tail for the accumulating Wheel of highest order does not effect acarry, but acts as a stop for said accumulating wheel when taking atotal. It is yieldingly held in obstructing relation to the pins 83 onsaid wheel by a spring 70, similar to the springs 7 5.

The stops 71 are normally out of rangeof the bars 8 and10, and I preferto bring the said stops and the accumulating wheels into range of saidbars by a parallel movement which I accomplish in a novel manner.

Suitableoperating means are provided, which, when manual operation isemployed, may take the form of an operating lever 85 secured to anoperating shaft 86 journaled in the main frame, normally held in retracted position by springs 87 between the main frame andarms 88 on theoperating shaft. The operation of the operating lever, in its forwardmovement, causes engagement between the accumulating wheels and theaccumulating racks, simultaneously bringing the steps 71 into range ofthe contactparts therefor on the computing and extended-carry bars, andcauses return to normal position of the computing bars and -eX-'tended-carry bars, thereby transferring the result produced upon thebars by the key lovers to the accumulating wheels, and accumulating saidresult upon the total accumulation previously added into said wheels.

Upon the retracting movement of the operating lever, the accumulatingwheels, with theaccumulations added into the same, are restored tonormal positions. and looked upon the locking bar, and the carriage isreturned to normal lateral'position, ready for the next operation of thekey-levers in forming the next number. The mechanism by which theseoperations are accomplished will nowbe described. K

For bringing the accumulating wheels into engagement with theaccumulating racks and the stops into obstructing position, operatingarms 91 are secured to the oper ating shaft. (See Fig. 3.)

92-is a toggle-link pivoted at 93 to one of the arms 91. It has a socket04 in which a pin 95 on a lever 96 rests, the lever being pivoted to themain frame at 97. A spring 98 normally holds the wall of the socketagainst the pin 95.

The shaft 99 of the accumulating wheels ismounted upon an equalizingframe upon which the carrying stops 71 are also mounted. The lever 96has a part'lOO thereon which is arranged to engage theaccumulating-wheel shaft for raising the same when the said lever israised by the operating lever as stated. The equalizing frame preferablycomprises bell-crank sides 101 102 connected by the rods 73 and 74. Thebell-crank sides are preferably mounted about the accumu lilting-wheelshaft at the angle of the same.

, 103 104 are links secured at one end about a rock-shaft 105 journaledin the main frame and at their other ends are articulated at 106 to oneof the arms of the respective bellcrank sides. (See Figs. 3, 12 and 18.)107 are links pivoted at 108 to the machine frame at one end thereof,-;the other ends of said links being articulated about the accumulatingwheel shaft. The links 103 104- and 107 are of equal length, and beingrespectively articulated to one of the arms if the bellcrank sides andthe angle thereof, cause said equalizing frame to be raised. in parallellines upon elevation of the accumulating wheel shaft by the lever96,-thereby simultaneously bringing the accmnulating wheels into rangeof the accumulating racks and the stops 71 into range of the computingand extended-carry bars.

It is desirable that the accumulating wheels shall be positivelymaintained in en gagement with the accumulating racks until tion underthe pin 115 on the lever and maintain the accumulating. wheels andequalizing frame together with the stops 71 in raised positionthroughout the forward movement of the operating lever and the movementof the bars 8 and 10 for accumu lating upon the accumulating wheels.When this has been accomplished, and the operating-lever is beingretracted, a tappet 116 upon a link 117, articulated with one of theoperating arms 91-.at 11S, engages a trip 119 on the latch 111 forretracting the latch out of range of the pin .115, which thereuponpermits the lever 96 and the parts supported thereby to drop and againbring the accumulating wheels out of range of the accumulating racks andthe stops 71 out of range of, the enumerating bars. Each of theoperating arms 91 is articulated .with one of the links 117 ,betweenwhich links a locating rod 121 is mounted, the locating rodreciprocating in slots 122 of the main frame.

The computing bars havecontact-arms 125 pivoted thereon ,at 126, and theextended-carry bars have contact-arms 127 pivoted thereon at 128. (SeeFigs. 4;, 6 and 11.) Each of these contact-arms is provided with a notch129 in which the locating rod 121 is adapted to be received. The springs38 normally urge the contact-arms 125 into predetermined nonrigidrelatioiii I with the bars 8 and 10, urging the rear faces 1300f saidarms against the front end faces 131 of said bars. The contact-arms 125are also provided with lips 132 adapted to engage the computing bars forlimiting the movement of saidcontac't arms against the action of thesprings 38, these lips being provided as a safeguard because of therange of movement of the enumerating bars. The object of the non-rigidmounting of the contact-arms is to provide means for effecting the carryfrom a column of lower order to a column of next higher order, duringwhich the bar 8 or 10 effecting the carry has a longer than normal rangeof movement. When the locatihg-rod 121 is moved forward, it will bereceived against the contact-arms for returning the bars to normalpositions, the range of movement of said contact-rod being equal to thegreatest desired range of movement of the bars. When the stop 71 is inits normal or locked position the bar will be arrested in its normalposition, the contact-arm thereon, however, being swung on its pivotagainst the tension of the spring 38. If any stop 71 is released" fromits latch 72 the bar 8 or 10 corresponding thereto will continue itsmovement until it strikes its stop in its abnormal position,

thereby moving the accumulating wheel in mesh with its rack the distanceof one tooth and effecting a carry in that wheel.

It will be noted that upon depression of the key-levers the carriage ismoved to the left. For returning the carriage to normal position uponretraction of the operating lever, I provide one of the operating arms91 with a latch 136 pivoted thereto at 137, and adapted to engage akeeper 138 on an arm 139 pivoted about the operating shaft. (See Figs. 1and 2.)

140 is a carriage-shifter in the form of a bell-crank lever having afork 141' thereon received against a contact-part 1 12 of the carriage.

1 13 is a link articulated with the arm 139 and the carriage shifter fortransferring the movement of the arm 139 when engaged by the latch 136,to the carriage-shifter 140, for returning the carriage to normalposition, whereupon the latch is released from the keeper by having atail 1% thereof strike a releasing-lug 145 on the main frame, a spring 116 returning the shifter to normal position. I

Novel means are also provided for restoring the stops 71 into engagementwith the latches 72, (see Figs. 1, 2, 4t, 6 and 11,) and I prefer toaccomplish this by mounting the stop-rod76 in arms 148 secured to arockshaft 149 mounted in the main frame, the rod being arranged toengage the rear faces of the stops 71 and to be contacted by acontact-lug 150 on the carriage-shifter when said shifter is moved.

If it is desired to print the numbers resulting from the operation ofthe key-levers, the computing bars are each provided with typerepresenting the digitsfromlcipher to nine, as indicated by the knobs154 on the extensions 155 of the computing bars (see Figs. 2, 3 and 4:),the type being arranged to be respectively brought into range of asuitable platen, shown as a roller 156, arranged to be advanced orrotated in any suitable manner, not herein fully shown because wellknown. The type representing the cipher is normally in printing positionabove the platen. For imprinting the type upon a suitable paper or thelike received about the platen, a hammer 157 is provided, it beingunderstood that a suitable inking ribbon is also provided between thetype and the paper, or other inking arrangement provided for the type.The hammer is secured to a rock-shaft 158 mounted in bearings 159 of themain frame and is normally under tension of a spring 160 for urgingmovement of the hammer toward the computmg bars. (See Figs. 1 and 3.)The hammer is maintained in raised. posit-ion by a catch 161 which isengaged by a latch 163 is a link articulated with the link 117, at 164.The link 163 is guided by having a slot 165 in which a pin 166 isreceived on an arm 167 secured to the rock-shaft. During the beginningof the forward movement of the operating lever the. link 163 is movedforwardly. The link 1 3 has thereon a trip 168 pivoted at 169 andnormally in range with the latch 162. Upon forward move ment of the link163 the trip 168 disengages the latch 1.62 from the catch 161, whereuponthe hammer is forced toward the rear extension of the computing barswith a sharp blow under the action of the spring 160 for impressing thetype in line with the impressing part of the platen upon the paper orother transferring medium, the pin 166 during this movement moving inthe slot 165, whereby suliicient play is given to the hammer and therock-shaft to permit the. hamm e r-blow. Upon further forward movementof the operating lever, however, the rear wall of theslot 165 engagesthe pin and again raises the hammer and swings the catch 161 intoengagement with the latch 162, the latch being held in engaging positionby the spring 160. Upon retraction of the. operating lever the trip 168is allowed'to pass the latch 162 for being returned to trippingposition. The positions assumed by the computing bars as heretoforeexplained for locating the same in. proper re-. lation to theaccumulating wheels, dependtransferring medium which havebeen-transferred to the accumulating racks, in their proper sequence andproper columns. The type on the computing bars are normally slightlydistanced from the platen so as to prevent blurring or streaks upon thetransferring medium. The compnting bars as already stated are supportedon the carriage-rod 12 which is received through slots therein. They arealso preferably support ed at their forward ends upon a rod 170 securedbetween the sides of the carriageframe. The forward ends of thecon'iputing bars are normally depressed by means of the springs 38. Whennow the rear ends of the computing bars are struck by the hammer, withasharp blow as stated, these rear ends are momentarily dern'essed againstthe action of the springs 38, rocking upon the carriage-rod l2, andimmediately after striking the transferring surface are retracted tonormal position for leaving a clear sharp imprint.

The totaling mechanism of my improved device will now be described.

In taking a total, preferably the operative connection between theoperating device or handle and the accumulating wheels is renderedinactive, .the carriage is brought into proper lateral position forbringing those type-bars under the hammer which are arranged to act inconjunction with those accumulating wheels into which accumulations havebeen computed, the accumulating wheels are raised into mesh with theaccumulating racks, the computing bars are released by the tripping ofthe pawls for transferring the accumulations in the accumulating wheelsinto'the bars, whereby the accumulating wheels are also cleared by being returned to zero,the pawls are brought into proper engagement withthe proper rack-teeth, the total is recorded by the move- 'ment of theoperating device or handle, and

the parts are ret-urned to normal positions.

174 is a total key, normally retracted by a spring 175, which is adaptedto be depressed when it is desired to take a total. In the form shown,the carriage is first placed in lateral position so that the computingbars only of the height of order which have been accumulated, arebrought within range of the hammer, so that. the depiction of ciphers tothe left of the total number may be avoided. l accomplish this by aseries of carriage stops 176 in the form of bars normally out of rangeof the carriage,, (see Figs. 5, (l, 7, S and 9,) pivoted about arock-shaft 17? mounted in the frame, and movable in slots 178 of a plate179 on which the stop-bar (38 is located.

181 is an arm loose about the rock-shaft and has a pin 192 thereonengaged by a cam [83 on the total-key 174.

185 is a rocker-frame comprising sidearms 186 187 secured to therock-shaft and connected by a cross-rod 188. The rockfor urging up 'ardmovementof the stops when the rocker-frame is raised. The stops havethereon tongues 191 received between the teeth of the accumulatingwheels. \Vhen any tongue 191, corresponding to the cipherposition of anaccunnilating wheel, is re ceived in the super-depression 67, thestopbar raised into carriage-stopping position fo' arresting the*arriage at that position, and preventing recording of ciphers to theleft of the total accumulated in the wheels. It may occur, however. thatthere is a cipher between the end figures of the total or at the rightof the total number. In order to prevent the carriage stoppingprematurely, or before the whole of the total number is encompassed bythe catriage-position, the carriage-stops are provided with laterallyextending fingers 192. These fingers extend laterally above thecarriage-stops corre sponding to lower order-columns, so that if forinstance a ciphc' appears to the right of any figure in the total, thelaterally extending tingcr which is on the carriage-stop correspondingto said figure will maintain the cipher carriage-stop to the rightthereof in lowered position, this lowered position correspomling to theheight to which the tongue is permitted to rise when said tongue isreceived in the shallower depressions be tween the teeth of theaccumulating wheels.

The release of the escapcment dog 51 for permitting lateral positioningof the carriage is accomplished (see Figs. Fraud 7) by a trip 195. shownin the form of a stem 1% on an extension 197 of the arm 18?, the stemengaging a pin 198 on said dog for raising the inner end of said dog anddepressing the tooth end thereof out of engagementwith the*arriag'c-rack 552, a tail 199 on the rack making engagement withthefirst stop 176 moved into line therewith.

When taking a total it is desi'able that the raising mechanism for theaccnn'nilating wheels and stops be brought out of influence of theaction of the operating lever for the reason that, in the ordinaryoperation of,

the machine, the accmnulating wheels are brought into mesh with theaccumulating racks at the beginning of the stroke of the operatinglever, for transferring the keyetl'ccts on the computing bars to theaccumulating wheels, the conmuting bars being also returned to normalposition during the forward movement of the operating lever. Tn taking atotal however. the reverse of this operation takes place. The results inthe accumulating wheels are transferred to the ac cumulating racks andcomputing bars for locating the computing bars at correct positions forplacing the proper type above the '7 platen for striking e 3 positionsfor printing, and resetting said ac-' 202 in the frame.

means of the ham r. For accomplishing this an arm 201 is secured to arock-shaft (See Figsg-(S and 8.).

This arm has on it a pin 203 which is en gaged by the arm 186, moved bythe total ey, for raising the arm 201 and-bringing a pin 20; thereonupon a rest 205 of a'latch 206 urged toward said pin 204 by a spring207, The rock-shaft 202 has thereon a trip 208 adapted to engage a pin209 on a tail-' piece 210 of the toggle-link 92, thereby swinging saidtoggle-link out of range of 'the pin 95.. The accumulatii'ig wheels arethen raised, by the total-key into engagement with the accumulatingracks, for which purpose .(see Figs. 8 and 13), the total-key isprovided with a cam 215 which engages a pm 216 on a forward extension217 of. the arm 103 of the accumulating wheel raising mechanism. As soonas the accumulating wheels have been raised into mesh with theaccumulating racks, there is a portion 218 on the total key whichstrikes a pin 219 on a lever frame 220 having side arms 223 secured to arod 221 rocking 1n the main frame, said lever-frame comprisingacross-bar 222 having a trip-part 22 1 thereon coinciding in lateralposition to the hammer, the outer end of which strikes the pawls 21 onlyof those computing bars whose accumulating racks are in engagement withaccumulating wheels upon which accumulations have taken place, releasingthe pawls thus struck, and permitting the computing bars thus releasedto be forced rearwardly by the springs 38. This rearward movement islimited by having the pins 83 on said accumulating wheels strike therear ends of the latches 82, for positioning the correct type on saidbars in correct cumulatin wheels to zero.

As herembefore stated the movement of the computing bars andaccumulating wheels, during accumulation upon the accumulating wheels,is in one direction, indicated by the arrow a, (see Figs. 6, 8 and 11,)while the movement of the computing bars and accumulatin wheels .in'taking totals is in the opposite direction. In order-to avoiddetrimental effect by reason of any lost motion there may be between theparts when bringing the accumulating wheels backtozero in taking thetotal, I provide replacement fingers 226 for the accumulating wheels,(see Figs/ 4;, 6 and 8,) these replacement fingers being adapted tostrike the pins 83 on the accumulating wheels momentarily prior torelease of the accumulating wheels from the accumulating rackslILlflklng a 'total, and preferably before the total is oia tooth intakingia totalins eadoif lodgthe propen-1 total by ing against the rearface'of said tooth,.the momentary slight push given the accumulatingwheel by the finger will-replace the pawl in proper position against therear face of the tooth. For operating said fingers I mount them on aroclcshaft 227 having an arm 228 secured thereto, the arm being providedwith a pin 229 arranged v tobe engaged by the cam 215 on the total-key.The computing bars having'now been placed in proper relation forrecording the total, the total-key having been retracted by its spring,and the accumulating wheels thereby returned to normal position, theoperating device or lever is operated for causing-the hammer to strikeits blow in recording. the total and for returning the computing bars tonormal positions. The forward movement of the operating arm 91 also.causes a trip 230 thereon to engage a in 23lzonf'the latch 206 forreleasing the late Iii-11d permit ting the parts held thereby to bereturned to normal positions. (See Fig. 8.) By this operation themachine has also been clams, ready for fresh accumulations orcalculations,"
